STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 441,719, dated December2, 1890. Application filed June 2, 1890. Serial No- 353,994. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL G. TRAVIS, a

- citizen of the United States, residing at Leavcnworth, in the countyof Leavenworth and State of Kansas, have invented certain new and usefulImprovements in Station-Indicators; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing bad to the annexed drawing, making a part of this specification,and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements instation-indicators; and it has for its object, among others, to providea simple, cheap, and efficient device of this character, of few parts,and those readily assembled and not liable to get out of order.

I provide a rotary wheel carrying the indicating characters, and analarm sounded by the revolution of the wheel, dispense with springs orclock mechanism for revolving the wheel, and simplify and cheapen theconstruction.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawing, which,with the letters of reference marked thereon, form a part of thisspecification, and in which is shown a face View of my improved device,with the doors shown open and broken away, and parts in section.

Referring now to the details of the drawing by letter, A designates theinclosing case or box, of any desired size and material, beingpreferably a shallow rectangular box within which the principaloperating parts are inclosed, and provided with hinged door or doors B,one of which, if two are employed, should be provided with asuitableaperture a, covered by a transparent medium or not, as preferred,through which the indicating charactor is displayed.

B is a wheel journaled on a shaft or axle 1) within the case, andprovided upon its face with the desired indicating marks-such, forinstance, as the difierent stations on a line of railroad, or, it maybe, the streets of a city on the line of a street railwaythe particularThis lever near its free end has connected thereto in any suitablemanner one end of a rope, cord, or chain E, which passes under thepulley e, suitably journaled in the case, and its other end passesthrough an opening fin the top of the case, and is connected with oneend of the arm or lever F, which is fulcrumed at g on the top of thecase or a standard h rising therefrom.

G is a spring connected with the free end of the lever O, opposite theconnection of the cord E, and serving to normally hold the lever in theposition in which it is shown in the drawing, the other end of thespring being connected to the case in any suitable manner.

H are pulleys, suitably journaled one near each end of the arm or leverF, and I is a cord or rope passed over one pulley and under theother,with one end fixed to the case, as at 2', and

the other end extended to the conductor or any other desired place whereit may be operated. Two or more of these cords may be employed, leadingto different points, if desired, by placing two or more pulleys at eachend of the arm or lever F.

J is a bell fixedly secured within the case, and K is its hammer,carried by the springarm L, which is attached at one end, as shown at j,to the inner wall of the case.

L is a spring-arm, attached at one end to the end wall of the case, withits other end arranged in the path of the teeth of the wheel B, asshown. This spring-arm is connected with the hammer-arm by the link M,pivotally connected at its ends.

The operation is simple and apparent. Pulling on the operating-cordmoves the wheel B one notch in the direction of the arrow, and thedesired indicating mark is exhibited through the aperture in the door ofthe case. As the wheel moves forward the spring-arm L The parts aresimple, readily assembled, not 1 liable to get out of order, and thewheel may be readily set to any desired point by opening the door of thecase.

The device is designed to be placed in a car or a station, or any otherdesired point, and may be made as fanciful as the tastes of themanufacturer or purchaser may dictate.

\Vhat I claim as new isl. The combination, with the wheel having teeth,of the lever on the axle of the wheel, the pawl pivoted on the lever,the cord attached to the lever, the arm pivoted outside the case, thepulleys near each end thereof, the connection between the arm and thecord, and the cord attached at one end to a fixed support and passedover and under the pulleys on the arm, as and for the purpose specified.

2. The combination, with the case and the wheel within the caseandhaving peripheral teeth, of the bell within the ease, the hammerarm,also within the case, and a spring-arm, also within the case andconnected with the hammer-arm and actuated by the wheel, as set forth.

3. The combination, with the case and the wheel within the case andhaving peripheral teeth, of the bell within the case, the hammerarm,also within the case, of spring material fast at one end, and thespring-arm connected with the hammer-arm and actuated by the wheel, asset forth.

4:. The combination, with the wheel having peripheral teeth, of thebell, the hammer, the spring-arm therefor, the spring-arm L, at tachedat one end to a fixed support and connected with the hammer-arm andarranged with its free end to ride over the teeth of the wheel, and thecase inclosing said parts, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
